Well the good news is that at least it's a state's issue now. It was never right for the feds to make the call, especially when everyone knew it had absolutely no effect (ok 1.5%) on national oil consumption in the first place. The stunt in the video is a good example of why places need to set the speed limit appropriately however. It's just not safe to set it too low, and that video illustrates this, which seems to be their intention to do so. I would guess they only did it for about 2 miles or so; sufficient to get the point across.
